, vented a new and Improved Starting Hechanism for Explosive-Engines, of which the following is a specification.

My invention relates to the class of devices for mechanically starting an explosive engine, and the object of the invention is to provide a device of this class having numerous features of advantage and utility. A form of device in the use of WhlClPt-ilBSQ objects may be attained is illustrated in the accompanyingdrawings, in which- Figure 1 is a diagrammatic view illus- (rating the position and manner of operationof a device embodying my invention. Fig. 2 is a detail view on enlarged scale in central longitudinal section through a structure embodying my invention.

In the accompanying drawings the numeral 5 denotes an engine base arranged to M suitably mounted on a vehicle (not shown) an engine 6 being suitably supported on the base. The crank shaft 7 of the engine is rotatably mounted in the base and a drum 8 is supported upon and secured to the crank shaft to rotate therewith, the direction of rotation beingindicated by the arrow in Fig. 2 of the drawings. This drum incloses the starting mechanism and the main clutch, forming a case for such parts. The drum is formed to constitute one member of a starting clutch, the inner surface bei'ngbeveled as at 9 to cooperate with the other member of the starting clutch to be hereinafter described, and the drum has also on its inner surface a guidegroovc 10 extending around the inner surface of the drum. A recess 11 is formed in the inner .wall ofthe drum for the reception of a ratchet pin 12 seated on a spring 13. A single ratchet pin only is shown and described herein, but any number of such pins may be employed as desired: The drum has a hub 14 through which the crank shaft 7 extends, the latter being preferably enlar ed as at 15, forming a shoulder against which the drum seats.

One member of the starting clutch is mounted within thealrum upon the enlarged Specification of Letters Patent.

portion 15 of the crank shaft, this member constituting a reciprocating part of the clutch. This reciprocating starting clutch member includes a disk 16 having a sleeve 17 mounted upon but arranged 'to rotate independently of the crank shaft, and a flange 18 forming the contact portion of this member of the clutch. A shoe 19 of leather or like fibrous material may be located upon the flange to provide a frictional contact surface.

A collar 20 is secured to the disk 16 in any suitable manner, the means herein shown consistin of rivets passing through a lip 21 on the co lar and through the disk, securing the parts together. An anchoring ring 22 is mounted for movement longitudinally upon the collar 20 as by means of'studs on the ring engaging slots in the collar as shown in Fig. 2. A socket-piece 23 is located on the ring, having a socket in which an anchoring pin 24 is located. A winding spring 25 located within the drum has its inner end secured to the anchoring pin 24 and its outer end secured to the member 26 of a main clutch, a band 27 suitably securing the s rin to the clutch member. The main 0 ate 1 member 26 fits within an enlarged recess 28 in the drum 8, this clutch member being of ring form and having on its periphery ratchet teeth 29 arranged to engage the ratchet pin 12. Anti-friction collars 30 secured to the outer surface of the main clutch member 26, as by means of studs, are located in the guide groove 10. Any suitable number of these collars may be employed as requircd.

A reciprocating main clutch member is mounted for movement longitudinally upon the sleeve 17, this reciprocating main clutch member including in its construction a neck 81, disk 32, and flange 33, the latter being provided if desired with a shoe 34 of leather or other fibrous material forming a friction clutch surface.

A housing 35 is secured to the outer face of the disk 32, this housing having a neck 36 within which a connecting shaft 37 extends, said shaft connecting the crank shaft with the transmission gear mechanism located in the transmission gear case 38 and being s lined or otherwise suitably connected with the neck of the said housing 35.

A toothed starting disk 39 is located on the end of the sleeve 17 within the housing 35, and starting levers 40 are pivoted to the housing, projecting through slots therein,

the inner ends of \the levers being adapted to engage the teeth\on the starting disk and the outer ends of the levers to engage a toothed a tuating disk 41. The levers are actuated in one dlrection by means of springs 42, any suitable number of the levers being employed, in the form herein shown and described three being employed for use, one

I only, however, being shown.

Thefactuating disk 41 is journaled-in the slde parts of a startin lever 13 which straddles the housing nee 36, this lever at its lower end being pivotally secured to a block- 44. A main clutch actuating lever 45 arranged to be actuated by the cot is pivoted in the usual manner to a block {16, this lever enga ing trunnions upon the housing neck 36, he lever being actuated in a manner common to motor vehicles for operating the main clutch.

A clutch actuating spring 47, in the form of a spiral spring, surrounds the sleeve 17 and neck 31, this sprin thrusting against the disks 16 and 32, forcing them apart and tending normally to keep the clutch mem-' v.bers of each of the clutches in engagement.

While I have'shown and described herein the mechanism preferred by me asembodying my invention, I do not intend or desire to limit myself to the precise construction shown and described, as I contemplate vari ous modifications and arrangements of mech'' anism which may be used without departing from the scope or'intent of the i nvention.\

The operation of the device is as follows:

In the initial operation of thedevice the" ment are rotated, carrying the 'anchei-ing; ring 22 and winding the main spring'25., While the main spring is being 'Woundthe" other parts of the device are stationary, the ratchet pin 12 freely passing the ratchet teeth 29. When the spring has been Wound the force of the crank shaft 7 is then imparted through the spring to the main clutch member 26, which is rotated, being held in place within the drum 8 by the'collars 30 en- I gaging but freely moving within the guide groove 10.' The members of the main clutch being in engagement the connecting shaft 87 is operated to transmit the power to the traction mechanism in the usual manner, as through transmission gearing. iThe main clutch may be operated'as by the foot or manner. When the engine is stoppedt-he force of the spring in its effort to unwind is exerted upon the main clutch member 26, tending to rotate it in the direction indicated .mitted to the drum 8 through the ratchet teeth 29 and ratchet pin 12. The' drum 8 is prevented from rotating, howe :er, by reason of the engagement of the starting clutch, the

clutch and the outer end upon the drum through the connection'above described being balanced. When it is desired to start the engine by the use of myimproved starting disengaged, if not in that relation, and the lever 43 being operated tocause thr. ictuat ing disk 41 to engage the levers 40, said leengage the reciprocating member of the starting clutch from its coiiperating member. The force of 'the spring at this time is pie vented from exerting its influence upon the from rotating bythe starting levers which engage the teeth .upon the starting disk 39 and also upon the actuating d k 41. The force of the spring is thus exerted uponthe engaging the ratchet pin 12 transmit the the cylinder to start the engine.

It will be noted that the drum 8 is of quite material size and weight, being so preferably constructed, in order to embody the beting such features it will be found readily. to serve the double purpose of a fly wheel as well as a drum or clutch member, and when so constructed it will be found that a fly with to advantage. It willlalso be noted that the drum 8 and the member 26 of the main clutch together constitute 'a'casing in which is mounted the spring 25, thespring I ing interposed between the other endof the spring and the other element of thecasing,

by a backing ratchet device.
